The Pro Circuit T-4 system will offer considerable weight saving, when compared to the OEM exhaust system. The T-4 exhaust system is ideal for giving the racer more power and at a reasonable cost. The Pro Circuit T-4 exhaust comes complete with stainless head pipe that works in conjunction with the silencer to produce more power from bottom to top. The stainless steel header pipe and silencer offers increased strength and should give you years of trouble-free use. The Pro Circuit T-4 exhaust system is easy to repack by just removing screws and re-wrapping the silencer core. Pro Circuit T-4 exhaust system has the ability to take your bike off the track into the unbeaten path with the US forest service approved spark arrestor and the T-4 also meets the AMA sound restrictions.

Features a round aluminum body with extruded aluminum end cap and a nickle plated connector.

Quiet core insert available for reduced noise

Love it!

Korbin in ID – Machine this part was bought for: 2009 KAWASAKI KLX110

Comments On Oct 20, 2013:This pipe looks awesome and is very simple to install. Makes my 110 sound like a much bigger bike. I added it at the same time as a big bore kit and was very satisfied with performance gains.

Quick power increase

Danielle in KS

Comments On Dec 28, 2011:Awesome power gain, low and bottom end. Great mod for my crf 230.
You gotta get the crf 230 power up jet kit, to take full advantage of it.
And a bbr cdi box helps alot too.
